Step-by-step explanation:
In a bar graph, the length of the bar signifies the size of the data item. A spreadsheet program can automate the process, but you can do the job almost as easily by hand.
Answer:
Step-by-step explanation:
Substitution method:
y= -2x + 2
x - 2y = 6
so y = (-2x + 2)
Substitute into y
Hence x - 2y = 6 is:
x + 2x +2 = 6 (+2x because there was - in the equations so -×- = +)
3x + 2=6
Then bring 2 to the other side so
3x = 6-2
3x = 4
x = 3/4 or 0.75
To find y :
y= (-2 × 3/4) + 2
y = -1.5 +2
y = 0.5
That's all I can do for now!
Answer:
Option (2) 1.5
Step-by-step explanation:
Rule for the dilation of an image by a scale factor is,
Scale factor = 
= 
= 
= 
= 1.5
Therefore, scale factor was used to create a circle A' = 1.5
Option (2) will be the correct option.
